ByteBlaster with USB<->PP adapter?

Started by Unknown September 29, 2003
Hi all,

Does anyone know if Altera Quartus II (3.0+) will let me use a
parallel port to USB adapter?  I just got a new machine, in part so I
could upgrade to 3.0 from 2.2 (and in part so everything would go
faster), but it doesn't have a parallel port!  I basically have three
options: waste the only PCI slot in the machine for a parallel port
card, use a USB adapter, or special-order a manufacturer-special
parallel port interface for the machine with unknown lead time.

The question is basically: does Quartus II rely on it being a serial
port interface with the traditional I/O ports, or does it handle
anything that can drive a printer?

Shelling out $300 for the yet-not-in-existence USB-Blaster cable is
not realistic, nor is $500 for MasterBlaster which doesn't even handle
the active serial configuration devices.

I believe that it treats the port as a bit bashed parallel port and as such
requires it to look exactly like a parallel port.
so unless the USB <> parallel port has the same registers, it won't work.
But this is just a belief.

I would suggest you waste a PCI port.. but make sure that the parallel port
card you buy can be returned if it doesn't work.  Not all parallel ports are
created equal.

Peter,

    I asked the experts at Altera, and they verified that using a parallel
port to USB adapter will not work.

Thanks. I ended up finding a vendor which carried the proprietary parallel port interface (really just a special cable plugging into a nonstandard header on the motherboard -- had they used a standard header the problem would have been solved long ago) for this machine and could deliver it with a reasonable lead time; FedEx is supposed to deliver it today. A USB solution would have been nicer because of portability, of course. -hpa -- <hpa@transmeta.com> at work, <hpa@zytor.com> in private! If you send me mail in HTML format I will assume it's spam.
